The difference between a DUI and a DUAC is that a DUI is a criminal offense and a DUAC is a moving violation. The DUAC will go on your driving record, where it will remain for 10 years. I believe what the officer/prosecutor is trying to tell you is that the records regarding the criminal DUI charge will be expunged after you plead guilty to the DUAC, such that it can no longer be found on a criminal background check. But the DUAC will still be on your driving record. Hope this helps, good luck.
